marking two-dimensional code on pcb board by uv laser marking machine

UV laser marking machine marking effect

UV laser marking machine is new laser marking machine which come out in nearly two years , its superior marking effect got the majority of manufacturers favored. Previously mainly rely on fiber laser marking machine and carbon dioxide laser marking machine to do mark. Although the fiber and carbon dioxide can be engraved in the general material marking, but because of its machine's own restrictions, can not achieve more refined, better effect. Such as use fiber laser to marking plastic, if fast, marking effect is not clear, if slow, plastic surface will be blistering, hand touch will obviously feel bump feeling.

The emergence of UV laser marking machine completely solve this problem, UV laser marking machine laser processing into a cold processing, because the high-energy molecules of ultraviolet photon, the need to directly deal with the metal or non-metallic materials above the molecular detachment, However, this detachment led to the separation of molecules with the material, this way of work does not produce heat, because it does not produce heat and the way the work of ultraviolet laser processing has become a cold processing. This is the difference between fiber laser and UV laser.

What is the application of the UV laser marking machine? UV laser marking machine is currently mainly used in some fine processing of high-end market, metaphor said some of the polymer packaging materials, flexible PCB board marking, silicon wafer micro-control, LCD LCD glass two-dimensional code to play Standard, all kinds of metal, plastic, building materials, communications equipment, etc. All above, can be used the UV laser marking machine.

Soldering machine support spot soldering, drag soldering and press soldering.

Automatic Soldering machine are mainly three soldering style, press soldering, spot soldering, drag soldering. Different soldering machines in different welding methods have its advantages. We can decide to choice the soldering machine according to the characteristics of the welding products.

Press soldering mainly solder joint need testing tension requirements, and the solder distribution is more uniform, no plug-in products, flat solder joints, you can use pressure welding. For the tensile requirements of the product is best to use automatic soldering machine solder, which is more match with clients requirement.

Drag soldering, the main requirements of the uniform distribution of solder joints and solder spacing greater than 0.1mm, this products need fixed plug. If the two solder joints are less than 0.1mm apart, do not need to fix the plug, if still use drag soldering will lead to product tin problems, this products using wave soldering or rewinding is better. The advantage of automatic soldering machine is to save time and improve efficiency.

Spot welding, products is mainly uneven distribution of solder joints or solder joints require high fullness. Of course, there is a case where the solder joints of the product are evenly distributed, but the inserts need to be fixed, which requires that one of the points be fixed and solder again. Because many products are uneven distribution of solder joints, usually choose spot welding, use automatic soldering machine to spot welding, with high efficiency.
